Why does the conductivity of a solution decrease with dilution?
3 Answers
Sunil Kumar FP
On dilution the volume of the solution is increasing but the number of ions that carry charge in a solution remains the same. Hence the number of ions per unit volume that carry charge in a solution decreases. As the movement of these charges towards the oppositely charged electrodes causes the flow of current, the conductivity of a solution decreases on dilution.

Conductivity of a solution is the conductance of ions present in a unit volume of a solution. On dillution, nomber of ions per unit decreases .hence ,the conductivity decreases
